The recrystallization behavior of the rolled Fe82.2Ga16.8B alloy sheet suggested that the material was fully recrystallized and the distribution of grain size had become quite heterogeneous after annealing at 650 °C for 1 h. The strong primary recrystallization texture {111}<110> was developed by way of the discontinuous growth of {111}<110> grains. The magnetic field paralleling to the rolling direction promoted the development of η -fiber texture during primary recrystallization. The relation between secondary recrystallization texture and magnetostriction indicated that the cubic texture {001}<100> was obtained in secondary-recrystallized sheets, corresponding to the largest magnetostriction, and a deviation from {001}<100> texture resulted in a decrease of magnetostriction. The “jump effect” of magnetostrictive strain was obvious when the sample was subjected to compressive stress. Large magnetostrictive strains, λ//λ// of 171 ppm and λ⊥λ⊥ of −146 ppm, were observed for the annealed sheets with the thickness of 0.26 mm under 24 MPa compressive stresses.
► Fe–Ga–B sheets with good quality were successfully prepared by rolling process. ► The magnetic field promoted the development of η-fiber texture. ► Large magnetostrictive strain was achieved under compressive stresses.
